To all whom it may concern:

Be it known that I, JOSEPH H. STIL-ms, Jr., a citizen of the United States, residing at ABaltimore city, State of Maryland, have invented certain new and useful Improvements in Wire Clips for Concrete Construction, of which the following is a. specificoton. Y .f

This invention relates to Ymeans for se,` curing reinforcing bars-in position in molds for concrete work so as to prevent.- their displacement (and the consequent injury or ruin of the finished work) while the concrete is being poured or otherwise manipulated previous to settingr or hardening.

The general object of the invention is to provide improved means for this purpose especially adapted to the securing together of 1einf()rcin.9,"b:1rs which cross each other et right or other angles. f

A further object is to provide such se curing means of such n. character that the concrete worker may make them himself at the4 work, to suit general or particular forms.

A further object is to provide securing means with improved means i'or supporting: the secured together bars at a suitable height from the bottom of the mold.

With these and other objects in view,'tlf1e invention consists in a clip or clampof the improved form', :uid of the material hereinafter fully described and afterward specifi'- cally claimed. f

In the accompanying drawings, which illustrate preferred embodiments of the invent-ion, Figure 1 represents, in perspective view, my improved clip asapplied to a pair of reinforcing' hars, crossing each other at substantially a right angle. Fig. 2 represents in perspective detail the clip before it. is applied to the reinforcing bers. Fig. 3 represents s. sectional view ou a plane cuttingzthrough o. concrete structure alongside of one of two crossed :reinforcing hars,fsl1ow ing the other bar in section, with my irney proved clip being shown applied to the cross hars, in elevation. Fig; 4 represents a view in elevation'of the clipin the form of Fig. 2 applied to the 11W@A .CrestedreinforcinghersY prior to mekigeljend in the-clip which locks it in position on the bars. Fig. 5 represents e view similar to Fig. .1 ofa modified form of-clip. Fig. 6 represents-the modified form of clip of Fig. 5 in perspective, un'epr plied to reinforcing bars'. Fig. 7 represents a. View in side elevation, of two 4crossed reinforcing bars, with my `improved clip applied thereto. Fig. 8 represents, in similar view, the parts shown in Fig. 7, looking at i v the opposite side. 6l.

' Like reference characters mark theV same parts wherever they Aoccur in the various figures ofthe'drawings.

Referring specifically to igs. 1 to 4,inelusive, of the drawings A and B indicate reinforcing hars which lie horizontally and cross each other in contact and which are especially intended iu` this position4 as rein forcemeuts for horizontal concrete constructions, such as oors, and `the like,`es et C. 7@ In Fig. 2 my improved clamp is shown in. the form in which it appears before apply- .ing it. `to the crossed hars A and B, each end ofthe wire heing'bent to forni vertical legs or supports. at 1 and 2, the former np 75 peering iu this ligure in the position it assumes when the clip is applied to the bars*- and the latter inverted, from which inverted position it is reversed during the process of applying the clip to the bars as herein 30 after explained. Each of thesplegs or'supports 1 and 2 is formed byrbeniling the wire atits opposite-'ends into Vparallel.stretches7 as at 3 andLQnd and 6, respectively and at the inner extremity "of tlie perallel 85 stretches, as at 7 and 8, the Wire is bent into curves, as at 9 and 10,theV cllrve 9 being reversed in position from the cnrve 10. In the preparatory form shownoin Fig. 2, the outer ends of the two cfurves 9 and 10 are 90 connected by a long, nearly straight stretch 11, the connection of this stret/ with curve Q'Eing in Athe forni of a. reversed cur-ve 12, and with curve 10 in the form of an angle, at 13. Y*The clip cztrteted as described, `and as illustratedvin Filis: f2 and 4, is applied to the crossed bars A und B by passing the curve 9 under 'the bar B sindl the reverse curve 10 over the har A, as shown in Fig. 4, in which" position the long connecting No stretch 11 passes under the har B. To lock the clip in position, the Wire of the stretch 11 is bent into e. loop 111, around the bar B, that pai-trofV the stretch V11 not used in the imp extending-along aleen, A, and nie ieg 1 or support 2. being reversed from the in` verted position of Figs. 2 and 4: to the u Y right position'of Fi s. l and 3w'ith t e *loop leirtmingun er andforrning a rest or support. vforthe bar A, `the legs 1 and 2 110 restingupon the bottom of the mold in4 which the concrete, as :it 15, Fig.' 3, is shaped, ziiid the bars A and B being clamped ltogether and supported in' the loops 10 end 9. 1

in the niodiiied forni of clip illustrated in Figs. 5 tcl8, ii'iclu'sive, the clip is of the saine 'torni as liereinbeore described and shown in Figs. 2' and inclusive, except that the leg or support 2 is omitted,nnd owing to this omission `the iniiniiei of applying the clip to the 'crossed bars .A and B is sliglitll7 modified. In suoli application, the stretch ll.. 'is not bentunder end around the bnr B, forming the -loop 14 but the curve l0 is simply engi-iged over the top of the ber A, with the .resulttliat the bnr B is supported inthe loop curve 9 und the bai" A. held in contacty with bar. B by the loop 12, :is in4 the construction of Figs. 1, 3 and 4:, ilieiatter function being-assisted, and the clipheld .in position, bythefengngement of the curve 10 over the top of biirA.l y

"living thus fully described'iny invention, what I cleini :is new and, desire to secure by Letters Potent of the United States isl. A wireclip for securing toget'lier'crossing bars for concrete reinforcementeom' lprising an uprightleg or support at one end, l

anzfidjneent downward curve for engaging iinderpne'of the bers, bends in the Wire extending` in position to pass over 'thejsecond bar' and under the .first bor, and a support an adjacent downward/o curve for engaginguiider one `of the ba"rs,fbends` iii the wire extending in position to 'pass over the seeend bar and under the iii-st bei' and" a, support at the other end of the wire, lseid sup-k Presence port being inverted in position with relation to the first mentioned support.

3. A wire clip for securing togetherl crossing bars for concrete reinforcementcompris ing an upright leg;t or support at 0ne.eii( :in adjacent. downward cuive for engaging under one of the bnrs, bends in the wire extending in position to pass over the second y bnr und under the first bi'ir, and :i curve and :i second support :it the other end of the wire. v

4i. A wire clip for securing together cross ing bars for concrete reinforcement comprising :in upright leg or support :it one end, :in

wire, said curve and support being reversed with relation to the first mentioned curve and support.

5. A clip for securing together crossing bers for concrete reinforcement made of a single piece of sti il' lfiexible wire, ssiid wire hiivino two iuriillel stretches :it lone endl forming avigertienl leg or support, n downward curve beginning :it the upper end of the leg, :i loop formed 'of n continuation of the Wire from the end of snid curve, ii long substantially horizontal' stretch beginning at the termination of. said loop, nn upward Vcurveiit the terininiitioi'i of'snid long stretch, and two parallel vertical stretches beginning at thee-termination of tlieliist named curve forming an inverted leg` or support.
